Abstract

PURPOSE: To simplify the construction of a work platform on the water, by specifying the manner of securing pinions and the manner of contact between racks and the pinions.
CONSTITUTION: Supports 11 are upright and are secured on an upper surface 10 of a float body 1, several pairs of spaced apart pinions 12AW12D are rotatably supported vertically along the supports 11, and tooth profiles of each of racks 9A, 9B and the pinions 12AW12D are selected such that major part of reaction force against the external force acting on the work platform becomes vertical along a support leg 2 at contacts between the racks 9A, 9B and pinions 12AW12D. Consequently, even if a force acts to move horizontaly a rigid member 6 equipped with the racks 9A, 9B, its major part is converted to a ivertical force to be transmitted to the pinions 12AW12D, so that the strength of the rigid member 6 in a horizontal direction can be reduced, nearly only a vertical force will be taken into consideration with respect to the support 11, and the construction of the work platform can be simplified.
